Vibration testing device

Abstract

A vibration testing device with a platform, a vibration assembly, a housing and a cooling system is provided. The platform is adapted to hold a test object. The vibration assembly is adapted to force a vibration to the platform. The housing has an inlet end and an outlet end opposite the inlet end. The housing is disposed under the platform and covers the vibration assembly. The cooling system with a fan and an atomizing assembly, and is disposed on the housing. The fan is adapted to generate an airflow. The atomizing assembly is adapted to generate atomized water. The airflow with the atomized water passes through the inlet end, the interior of the housing and the outlet end sequentially to reduce the working temperature of the vibration assembly.

What is claimed is: 
     
         1 . A vibration testing device, comprising:
 a platform for holding a test object;   a vibration assembly, adapted to force a vibration to the platform;   a housing having an inlet end and an outlet end opposite the inlet end, the housing being disposed under the platform and utilized for covering the vibration assembly; and   a water cooling system having a fan and an atomizing assembly, the fan being disposed at the outlet end of the housing, and the atomizing assembly being disposed at the inlet end of the housing;   wherein the fan is adapted to generate an airflow through the inlet end, the interior of the housing and the outlet end sequentially, the atomizing assembly is adapted to generate atomized water, and the atomized water is thus guided by the airflow through the inlet end, the interior of the housing and the outlet end sequentially to reduce a working temperature of the vibration assembly.   
     
     
         2 . The vibration testing device as claimed in  claim 1 , wherein the inlet end is disposed on an upper portion of the housing, and the outlet end is disposed on a lower portion of the housing. 
     
     
         3 . The vibration testing device as claimed in  claim 2 , wherein the inlet end and the outlet end have at least one inlet and at least one outlet respectively. 
     
     
         4 . The vibration testing device as claimed in  claim 1 , further comprising an air supply system disposed at the inlet end. 
     
     
         5 . The vibration testing device as claimed in  claim 1 , wherein the water cooling system further comprises a control unit for controlling the strength of the airflow generated by the fan, and control the water amount of the atomized water generated by the atomizing assembly. 
     
     
         6 . The vibration testing device as claimed in  claim 1 , wherein the vibration assembly comprises at least one vibration unit. 
     
     
         7 . The vibration testing device as claimed in  claim 1 , further comprising a plurality of transformers disposed in the housing.
